They have received a few reports of excessive virtual memory consumption
(one report was from me!)
and they are looking into it. In the meantime if your VM gets out of hand,
what you can do is kill the process CAVTRAY.exe and all of it's child
processes with a tool like process explorer from:
http://www.sysinternals.com/ntw2k/freeware/procexp.shtml
or just don't bother letting CAVTRAY.exe run at all (I removed it from the
startup list in the registry using another tool from the above site -
autoruns
I am waiting for CA to fix this problem too... but in the meantime, I can do
without the tray application; if I need it for anything, I can just manually
run cavtray.exe
a bit of a bother, but otherwise the product works extremely well IMHO
